Assignment: Introduction to Arduino and Physical Computing

Collaborators:

In this project, I first made one LED blink, then I got two LEDs to blink alternatively

I used:

• 2 Light Emitting Diodes
• 1 220-ohm Resister,
• Arduino Board
• Breadboard
• 4 wires

The Source Code, modified to blink two LED's attached to outputs 12 and 13

/*

 * Blink

 *

 * The basic Arduino example.  Turns on an LED on for one second,

 * then off for one second, and so on...  We use pin 13 because,

 * depending on your Arduino board, it has either a built-in LED

 * or a built-in resistor so that you need only an LED.

int ledPinBlue = 13;// LED connected to digital pin 13

int ledPin = 12; //LED connected to Digital pin 12

void setup()                    // run once, when the sketch starts

{

  pinMode(ledPin, OUTPUT);      // sets the digital pin as output

  pinMode(ledPinBlue, OUTPUT);

}

void loop()                     // run over and over again

{

  digitalWrite(ledPin, HIGH);   // sets the LED on

  delay(500);                  // waits for 1/2 seconds

  digitalWrite(ledPin, LOW);    // sets the LED off

  //delay(500);                  // waits for 1/2 second

  digitalWrite(ledPinBlue, HIGH);

  delay(500);

  digitalWrite(ledPinBlue, LOW);

  //delay(500);
